Way to Optimum Delivery

The installation of boiler optimisation controls to 77 boilers across the Renfrewshire Council estate has led to significant savings.

Sabien was asked to provide measurement and verification to demonstrate the levels of cost savings being achieved.

Using the council’s consumption data and regional degree day data an average reduction of gas consumption of around 14% with a 1.7 year payback was calculated by the use of Sabien’s M2G boiler optimisation controls.

The project to improve boiler optimisation by retrofitting M2Gs forms part of the council’s current carbon management plan (CMP) that has been developed in partnership with Resource Efficient Scotland. As such, it builds on an earlier CMP which achieved a carbon reduction of 28.35%.

M2G works alongside the existing controls and BMS strategies, e.g. sequencing, weather compensation and demand based control to deliver further savings. It is reportedly widely recognised as a key initiative to reduce energy costs for many private and public sector organisations.

“We are continually evaluating opportunities to further reduce energy consumption and recognised that boiler dry cycling was a potential problem,” said Craig Doogan, Energy Team Leader, Renfrewshire Council. “The M2Gs were installed across our estate quickly with minimal impact on our operations. The post-project verification using CUSUM analysis provided by Sabien clearly indicates the savings being achieved are in line with our expectations.”
